Do you believe in an objective morality capable of being scientifically investigated (a la Sam Harris *or others*), or are you a moral nihilist/relativist? There seems to be some division on this point. I would have thought Less Wrong to be well in the former camp.
Edit: There seems to be some confusion - when I say "an objective morality capable of being scientifically investigated (a la Sam Harris *or others*)" - I do NOT mean something like a "one true, universal, metaphysical morality for all mind-designs" like the Socratic/Platonic Form of Good or any such nonsense. I just mean something in reality that's mind-independent - in the sense that it is hard-wired, e.g. by evolution, and thus independent/prior to any later knowledge or cognitive content - and thus can be investigated scientifically. It is a definite "is" from which we can make true "ought" statements relative to that "is". See drethelin's comment and my analysis of Clippy.
"Objective" means "mind-independent" so if you're looking at someone's mind to determine those values they're, by definition, subjective. When we use the words "objective" and "subjective" in meta-ethics we're almost always using them in this way and now questioning, say, whether or not there are objective facts about other people's minds.
Not quite, I don't think. If you are looking at different well-functioning well-informed minds to get the truth value of a statement, and you get different results from different minds, then the statement is subjective. If you can "prove" that all well-functioining well-informed minds would give you the same result, then you have "proved" that the statement is objective.
